kconfig_lint: Exclude some Kconfig symbols from unused symbol checks

The configuration that coreboot uses for setting selected symbols
typically involves a structure like this:
config BLEH_SPECIFIC_OPTIONS
def_bool y
select SYMBOL

This leads to an an extra kconfig symbol BLEH_SPECIFIC_OPTIONS
that is never referenced by anything else, generating a warning.

Since this is currently the construct that coreboot uses, filter it
out of the warnings for now.
